Short summary

Sheep milk production and ingredients are influenced by genetic and environmental factors. In this study, we implemented selection signature analysis to identify candidate genes related to ovine milk traits. The results revealed six selection signature regions showing signs of being selected (P < 0.001) located in chromosomes 1, 2, 3, 6, 13 and 18. In addition, 38 QTLs related to sheep milk performance were identified in selection signature regions, which contain 334 candidate genes.
